I have an old Celstar Deluxe Drive that I’m hoping to use for guiding. There is a port for the hand controller that I hope to use for the ST4 cable from my ZWO camera (run by asiair mini).

The problem is the pinout could be wrong and it does appear to be backwards from the info I’ve found. If I get it wrong, I could blow the electronics. Does anyone know whether I can use this hand control port for an ST4 cord to guide?
